2500 KN Clamping Force Silicone Vulcanizer Double Stations 250 mm Plunger Stroke

The flat belt vulcanizing machine is one of the vulcanizing machine equipment, and its equipment features are as follows:

1. Flat plate vulcanizing machine The hot plate has a large specification, so it is generally composed of a hot plate.
2. In order to ensure uniform heating, multi-stage steam heating is usually used.
3. Generally multi-cylinder type.
4. The two ends of the hot plate have a transition zone of 200-300 mm width from the edge of the plate. In this zone, the cooling hole is cooled by another drilling channel to prevent the sulfurization of the intersection of each section of the flat zone due to two vulcanization.
5. There are horns on both sides of the flat belt to ensure the width and thickness of the flat belt. In order to make the flat belt under sufficient pressure to improve the adhesion strength between the rubber layers, the thickness of the horn should be 25-30% thinner than the thickness of the semi-finished products. . (The horn is replaceable)
6. It is provided with a clamping and elongating device for pre-stretching the flat belt before vulcanization, so that the cord is evenly stressed during the working process, and does not cause rapid tensile deformation (elongation) during use. .

(This is because the tape will bend and deform the cord during the rolling, cutting and forming process, and the material itself will be stretched and deformed. In the process of pre-stretching, the tape will be solved before vulcanization to ensure the use. The deformation is small. The size of the elongation depends on the raw material of the flat belt and is determined by the experimental method. The elongation treatment can promote the uniform tension of the layers and reduce the permanent elongation of the product. The extension of the belt with the core made of cotton fiber cloth The elongation rate is 10%, the elongation of the conveyor belt is 3-4%, and the elongation of the conveyor belt and the transmission belt made of synthetic fiber fabric is even greater.)

8. For flat belts of heat-shrinkable textiles (such as nylon), a post-elongation cooling device shall be used to prevent the flat belt from elongating rapidly during use.
9. Microwave preheating can be adopted to uniformly heat the flat belt to about 100 °C before entering the vulcanization, thereby shortening the heating time of the flat belt in the vulcanizer and improving the production capacity.

The flat vulcanizing machine is equipped with various auxiliary machines to form a flat belt vulcanizing machine production line.

In the production process of using flat vulcanizing machine, we must understand some safety operation requirements to avoid safety accidents. Below we list some basic safety operation procedures, I hope the operators can take it seriously.

1.  All molds must be centered when placed in the flat plate. Take the gloves with the mold to prevent burns.
2. When the test piece is stuck, open the mold and be careful to prevent it from falling.
3. Adjust the pressure gauge according to the die size and the specified unit pressure. It is strictly forbidden to overpressure vulcanization.
4. It is strictly forbidden to accumulate uneven plates in the flat plate.
5. When cutting the sample with the vulcanized board, the protective rubber sheet must be placed.
6. If the equipment is faulty, the power must be cut off before processing.
7. When taking the test piece from the mold, pay attention to the cavity of the cavity and the surface of the die to protect it from scratches.
8. It is strictly forbidden to take the mold or clean up the debris when the flat plate is raised.
9. Do not use the flat vulcanizing machine beyond the specified temperature.
10. When not in use, turn off the power, put down the pressure, and close the oil valve.
